Bespoke Solution with High Temperature Wheels for Fabwell Ltd

High Temperature Wheels – A Case Study

BIL Group custom build a rail wheel and axle assembly, as a bolt on solution for use in a furnace environment.


Bespoke High Temperature Heat Treatment Wheels.

Our client for this project was Fabwell Ltd. They are one of the UK’s biggest design and manufacture specialists of heat and corrosion resistant alloy fabrications, furnace spares, repairs and modifications.

The requirement was to design and manufacture a charging carriage running on rail sections, feeding a copper annealing furnace in a high-volume production facility.


Crucially the wheels used needed to withstand a temperature of 250 degrees centigrade for a period of 5 minutes to resist radiated heat when the furnace door is opened. The wheels are required to guide the carriage accurately to negate probable alignment issues. The carriage needed to travel in a straight line using flanged rail wheels. The load capacity requirement of the carriage was 5 tons.

The bearings needed to withstand elevated temperatures and have an accessible greasing facility. A ‘bolt on solution’ was required to ensure a minimum installation time on site.

The project needed to be completed within a set timeframe to hit the client’s factory shutdown window.


We used double flanged wheel sets to provide guidance on the rail. These wheels were manufactured from high tensile grade steel and fitted with high temperature rolling element kiln car bearings, installed with high temperature grease and a ‘through axle’ greasing facility.

The Bolt On capability was achieved using pinch bracket type mounting blocks, positioned on a common axle, with the wheels mounted at each end and secured with a lock nut and tab washer arrangement.

Bespoke axles gun drilled and cross drilled provided a through axle greasing facility, with the grease nipple positioned at the end of axle to enable ease of lubrication from an accessible location.

Wheel sets were mounted in series along the length of the carriage to spread the 5-ton load and to offer support whilst maintaining consistent guidance on the rail tracks.

Axle pinch brackets enabled quick and easy installation using a simple 4 bolt fixing method which located precisely into pre-drilled holes on the underside of the carriage fabrication.


The solution we provided allowed significant energy savings and increased productivity levels to be gained through improved cycle times, allowing faster through put of heat-treated materials, which in turn resulted in savings on gas consumption due to reductions in heat loss through furnace door needing to be open for less time.

Paul Dickens Managing Director at Fabwell Ltd commented after the installation had been completed; “I am Very pleased with the outcome of this project and look forward to working with BIL on future projects”.
